Custom string format for collection members?

[Oskar Berggren]

Hi,

I have a collection of objects that I test together with
Has.Member().Using(custom comparison). When the element isn't found,
nunit prints a string representation of the actual collection.
However, because the objects in the collection doesn't override
ToString(), this printout is rather meaningless.

Overriding ToString() for this type is not possible.

Is it possible to specify a custom "object formatter/renderer" that
NUnit will use to get a string representation of each collection
member?

Hi Oskar,

You can provide a custom constraint, which combines a custom comparison
with the sort of renderer you are looking for. To use it, you could write
something like Has.Member.Matches(new MyConstraint(<args>))
